Engine and Engine Cooling › Exhaust System

Filed Jun 10, 2002IL

CONSUMER HAS SIX 1997 B7 WITH 20000 MILES OR LESS AND THEY ARE ALL HAVING THE SAME PROBLEM. THE PROBLEM IS WITH THE DESIGN OF THE SEAL FOR THE EXHAUST BETWEEN THE MANIFOLD AND THE PIPES. THE DESIGN WAS CHANGED FROM CONSTANT TENSION TO A SOLID COLLAR WHICH IS CAUSING THE EXHAUST TO LEAK. *JG THE CONSUMER PURCHASED TWO 2001 G30 CHEVROLET MINI BUSES WITH 5.7 LITER ENGINES ONLY TO FIND OUT THAT THEY HAVE THE SAME DEFECT AT ONLY 4000 MILES.

Reading this record

No unusual pattern of severe incidents in the complaint record.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Most recent recall on file: none. Source: NHTSA Office of Defects Investigation.
